When a fan buys a ticket, we learn an enormous amount about them: What bands they like, where they live, how much they are willing to spend. Someday, a fan will be sitting in a bar and his cellphone will text message 'Sonic Youth are playing tonight. Do you want to go?' He'll buy his ticket over the phone and walk to the concert.

The touring business is obviously critical to selling records, building fan bases, selling T-shirts, fulfilling sponsorship commitments.

We can't say to a Ticketmaster venue that says they want to use a different ticketing platform, 'If you do that, we won't put shows in your building.'

I was diagnosed with a lung disorder that some people walk around with and don't even know they have. Through early diagnosis, I'm happy to share that I stay healthy with diet and exercise.
